Patent EP-0029904-A2 (EP)
Inventor: WOLF FRANZ JOSEF
IPC: F16L21/02
Filed: 1980-10-15
Abstract: A ring-packed pipe spigot-and-socket connection in which an elastic rubber packing ring having an essentially V-shaped cross section is disposed in an annular groove provided in the inside wall of a socket in such a way that prior to the insertion of the spigot end, one of the two legs of the V-shaped packing ring lies substantially axially aligned and turned toward the outlet of the socket, while the other leg extends substantially radially into the interior of the socket. After insertion of the spigot end, the two legs of the V-shaped packing ring provide a seal at the external wall of the spigot end. In the process, the segment of the packing ring facing the two sealing legs, i.e. the "foot segment", seals against the bottom of the annular groove. The annular groove has the shape of a substantially shallow V-shaped chamber and is of such a width that it can accommodate the spread-out packing ring completely when the spigot end has been inserted in the socket. On its two axially opposite ends, the annular groove is bound by radially extending circular ring surfaces, whose radially innermost edge is defined by the intersection of the surface with the cylindrical inside wall of the socket. The foot segment of the packing ring is of toroidal design in the manner of the ball of a ball-and-socket joint and rounded off relatively flatly or shallowly. It lies in a recess whose profile is complementary to the profile of the foot segment and which has been provided axially approximately in the center of the circular groove having been designed in a shallow V-shape. This recess acts as an annular socket like that in a ball-and-socket joint for the foot segment of the packing ring. It accommodates and blocks the foot segment of the packing ring against axial displacement, but permits flexure of the ring in the recess of the groove. The recess is preferably slightly undercut in the direction toward the base of the socket.

Abstract: The present invention relates to the discovery that the administration of maltol or ethyl maltol at appropriate dosage levels and rates, significantly reduces the tobacco consumption of habitual smokers. In a preferred embodiment, finely divided ethyl maltol is distributed in a chewing gum base, which when chewed by the subject, results in a gradual release of ethyl maltol into the oral cavity. When administered in appropriate amounts over a period of several days, there results a gradual decrease in the number of cigarettes smoked and the length of time they are smoked. The reduction appears to be spontaneous and does not appear to be accompanied by the typical symptoms of nicotine withdrawal.

Abstract: For punching a card which is continuously moving as it is being punched, the punch element (77) is pivoted to an actuating lever (63) and pivots against the force of a spring (84) as the card moves. The spring returns to the punch to its initial position when the card has passed the punch station. A solenoid (66) pivots the actuating lever. Provision is made for adjustment of the distance of penetration of the punch. A resilient roller (87) engaging the face of the card opposite the punch backs up the punch. The card has two separate magnetic tracks, defining respectively a security code and the number of uses remaining on the card. The other track is a control having signals which are read directly proportional to the speed of movement of the card. The card is inserted in a slot in a machine which takes in the card into the machine, reads the data on both tracks, reverses the direction of the card, and impacts the card with a hole to indicate that it has been used once. The position of impact is controlled by the number of uses of the card prior to the particular use and the control track. While the card is travelling in the reverse direction the first track is re-recorded with the number of remaining times of use and a security code at a rate determined by the control track.

Abstract: An industrial process plant has data concerning its inputs and outputs fed to a control apparatus which optimizes operation by an optimization procedure using linear programming. The plant includes components which can be switched between idle and run states. A process model representing the plant includes a plurality of constraint functions and an objective function which is to be minimized or maximized, the latter function including terms for each idle/run component representing a change in its status. A model updating procedure updates the parameters of the process model in accordance with the current process state, including setting the signs of the coefficients of the idle/run component terms in dependence on the current statuses of those components so that each such term makes a positive cost contribution to the objective function in the event of a change of status. A scheduling procedure operates the optimization procedure at fixed intervals and/or whenever the current state differs sufficiently from the most recent state set by the optimization procedure, or under operator control.

Abstract: Body structures into which a gamma-emitting isotope has been introduced are investigated using an imaging system comprising in sequence a collimator, a first detector, a filter, and a second detector. The first detector is partially transparent to the emerging photons and the filter is adapted to have an absorption edge energy fractionally less than the energy of the radioactive isotope source. The first detector produces an image of both scattered and non-scattered photons and the second detector simultaneously produces an image of only the scattered photons. The two images can be manipulated to produce an image due only to non-scattered photons which is the image of interest.

Abstract: A method for filtering a fluid medium containing solids, in a filtration zone having a filter, comprises maintaining a pressure difference across the filter, thereby obtaining a fluid filtrate, and introducing into the filtration zone a second fluid which is substantially immiscible with, and has a density different from, the fluid medium, in which the filtration zone is closed and in which the method is operated under conditions such that solids are maintained in suspension substantially throughout the filtration zone. 
     The method may be conducted by introducing the fluid medium into a duct 1 having a filter 2, removing the filtrate through a transport line 3, e.g. under the influence of a vacuum pump 6. The second fluid is air introduced via a Venturi pump 7.

Abstract: A method and apparatus for determining the rate of flow of a liquid in a region of a body using a nuclear magnetic resonance technique. Nuclear magnetic resonance is excited firstly preferentially in a slice (43) of the body which includes the region and then over the whole of the body. A period of time ( T ) is allowed to elapse, and nuclear magnetic resonance is then excited preferentially in the slice. The free induction decay signal is then measured, and the signal is related to the state of flow of the liquid through the slice (43).

Abstract: A Raschel Lace and a method of manufacturing such lace to form a base net whose openings display alternately a length of a first number of loops and a length of a second number of loops. Pillars of predetermined numbers are formed upon each needle then switched to the adjacent needle to similarly form a predetermined number of pillars on that needle, then switched to another needle to form a predetermined number of pillars on that needle so that a selected number of loops is created. The loops are connected after selected numbers of loops are formed so that predetermined openings are formed. 
     The size of the openings in the mesh thus formed may be varied by inlaying threads in a prescribed manner to either divide larger openings or to draw together wales at selected locations to accent the larger openings.
